EDWARD mean, 0] BLOOHING'DON, ILLINOIS, ASSIGNOB' TO MULLINS MANUFACTUR-ING- GOBPORATION, OI SALEM, OHIO, A CORPORATION OF NEW YORK WBINGERApplication. fled December 2, 1831. Serial No. 578,453.

The object of my invention is to provide an improved mechanism forreadily associating and dissociating the two coacting rollers of awringer.

The accompanying drawing illustrates my invention in an embodimentsuitable for ordinary household use.

Fig. lis a vertical axial'section in partial side elevation;

Fig. 2 is an end elevation with a portion of the end walls of the baseand cross-head broken away, and c Fig. 3 a fragmentary plan of one endof the base.

In the drawing 10 indicates a main frame or base, conveniently formed ofsheet metal,

and comprising hollow end standards 11,

oppositely extending aprons 12, guard wings 13, and an intermediatetrough 14 perforated in its bottom.

Each end standard is provided, in a common manner, with a verticalguide, open at its upper end, for the reception and support of usualbearing blocks 16 of the lower roller 17 and for the reception of usualbearing blocks 18 of the upper roller 19. The abovedescribedconstruction is well-knownin the art and, in detail, may be variedthrough a The upper end of each end standard 11 is open for thereceptionof mechanism, carried by the cross-head 20, now to be described.

The cross-head 20 is convenientl formed of sheet metal and so shaped an'proportioned as to slightly sleeve over the upper openends of the endstandards 11.

Secured within the cross-head 20 near each corner is a bracket 21 intowhich is adjustably threaded a dependin desired axial adjustmentiSleeved upon each end pair of bolts 22 are the outwardly-projecting feet24 of a bearin' abutment yoke 25 formed to overlie one o the bearingblocks 18.

, Journaled in each end of cross-head 20 is a short rock shaft 26 towhich are nonrotatively secured the arms 27 of a U-shaped lever 28 theintermediate portion of which extends lengthwise of and overlies thecross-head 20.

Nonrotatively secured to the inner end of bolt 22 held in y check nut23.

each rock shaft 26 is a cam plate 30 provided with an inwardlyprojecting arcuate cam segment 31 adapted to underhe an anti-frictionroll 32 journaled on a pin 33 carried by a cross bar 34 mounted in theupper end of standard 11. Thebearing blocks 18 may be secured in theyokes 25 or said yokes 25 may be merely slidably engageable with saidblocks. 6 l

Sleeved upon each bolt 22 and engaging the adjacent foot 24 is acompression spring 40 the upper end of which abuts a nut 41 on the bolt.

When the U-shaped lever is displaced to either extreme from its middleposition, the adjacent ends of the a'rcuatecam flanges will lie freefrom the anti-friction rolls 32 and the cross-head with its yokes,springs, cams, rock shafts and U-shaped lever may be withdrawn upwardlyfrom the base.

When the springs and yokes are reinserted in the base and the U-shapedlever is swung to its medial position, the cam flanges 31 will takeunder the anti-friction rolls 32 so as to tie the crossbar to the baseagainst upward displacement. Proper adjustment of bolts mounted atopposite ends of the cross-head and insertible into the end standards,springs interposed between the cross-head and abutment yokes, a leverstraddling the cross-head wlth its ends journalled in the cross-head onan axis longitudinal of the cross-head, and

means connected with said lever within the cross-head for separablyengaging the base within the cross-head by angular movement of thelever.

2.A. Wriuger comprising, a base having hollow end standards, acooperating ,crosshead, bearing-abutment yokes slidably mount ed atopposite ends of the cross-head and insertible into the end standards,springs ibterposed between the cross-head and abutment yokes, a leverstraddling the cross-head with its ends outsidethe opposite ends of. Ithe cross-head on an axis longitudinal of the cross-head, pivot shaftsconnected to said lever and projected into the opposite ends of thecross-head, a cam-plate carried by the inner end of each shaft, andcooperating pro- 1 jections carried by the base within the length of thecross-head and in positions to be respectively underlaid by portions ofsaid camplates.

3. A wringer comprising a base having hollow end standards, acooperating crosshead, two depending bolts carried at each end of thecross-head and insertible into the end standards, springs sleeved onsaid vbolts, a bearing-abutment yoke sleeved on each end 10 pair ofbolts, a lever extending lengthwise of the cross-head, pivot shaftsconnected to said lever and projected into opposite ends of the I crosshead, a cam-plate carried by the inner end of each shaft, andcooperating projec- 95 tions carried by the base within the length ofthe cross-head and in positions to be respectively underlaid by portionsof said cam plates. i x

4. A wringer comprising a base having hollow end standards, acooperating crosshead, two depending axially adjustable bolts carried ateach end of the cross-head and in sertible into the end standards,springs sleeved on said bolts, a bearing-abutment yoke sleeved on eachend pair of bolts, a U- shaped lever straddling the cross-headlengthwise, pivot shafts connected to said lever and projected intoopposite ends of the cross-head, a cam-platecarried by the inner end ofeach 40 shaft, and cooperating projections carried by the base withinthe length-of the crosshead and in positions to be respectivelyunderlaid by portions of said cam plates.

, In witness whereof, I have hereunto set my hand at Bloomington,Illinois, this 21st day of November, A. D. one thousand nine hundred andthirty-one.
